Abstract

L'invention concerne des procédés permettant d'obtenir des complexes du virus de l'hépatite C (HCV) et des particules de type HCV renfermant des gènes structurels du HCV. Dans un procédé, des cellules renfermant des particules de type HCV sont lysées avec de la digitonine, en présence d'inhibiteurs de la protéase. Du polyéthylène glycol est ajouté lentement au lysat, de manière à fournir un précipité comprenant des complexes des protéines structurelles HCV associées à des vésicules ou micelles lipidiques et des complexes renfermant des protéines structurelles virales sous la forme d'agrégats insolubles. Dans un autre procédé, le lysat est centrifugé dans un coussin de sucrose. Le culot est, de préférence, soumis ensuite à une ultracentrifugation à équilibre, de manière à fournir une préparation de particules de type HCV de dimensions hétérogènes. Le troisième procédé consiste à soumettre les cellules infectées à un choc hypertonique/hypotonique et à lyser les cellules avec de la digitonine, en présence d'inhibiteurs de la protéase. Le lysat est aggloméré et fractionné de manière à fournir une population de particules de type HCV sensiblement homogènes et possédant un diamètre moyen d'environ 50 nm. On entend par <= sensiblement homogènes >= que la forme des particules est similaire et les dimensions des particules varient d'au maximum 10 %. L'invention concerne enfin des procédés d'utilisation des complexes HCV et des particules de type HCV comme outils de criblage et de diagnostic, des compositions immunogéniques, ainsi que des procédés de traitement de patients présentant des symptômes d'une infection au HCV, au moyen de composés ou de substances interférant avec la liaison ou l'internalisation des particules de type HCV selon l'invention dans des récepteurs de l'asialoglycoprotéine.
